A Phone Case Inspired by Space Walks, Built for Trail Runs

Two Shark Tank contestants created the Phoozy to shield smartphones during outdoor adventures in the elements. (If you follow the show, you'll remember it sparked a three-way bidding war among the Sharks for a portion of the company.) The Phoozy-yes, like a beer coozy for your phone-is a five-layer thermal capsule made from spacesuit-inspired materials. Designers adapted the tech from NASA's radiant barrier insulation, which was developed for the Apollo Space program.

THE CLAIMS

• Drop-proof up to 9 feet

• Sinkproof

• Water-resistant

• Triples phone battery life

• Exceeds military impact standards

THE RESULTS

The XP3 protected a raw egg from breaking when dropped vertically from four feet, a little more than waist height. After 30 minutes inside a freezer at 11°F, the case's internal temperature remained just above freezing at 36°F. Phone batteries still drain fast in these temps. But the XP3 will help you squeeze out a little extra juice, as well as prevent roasting your fingers on a hot phone screen this summer. The biggest negative is that, like an astronaut's space suit, the XP3 is big and bulky. On the run, it was cumbersome to hold without a hydration pack or vest to stash it in.
